The intelligent self-defense body protection device comprises a housing and a strap disposed on one side of the housing and fixed to any position on the user body, the housing comprising: an inflation unit, a switch unit, a sensing unit, and a memory unit And a control unit, wherein: the inflatable unit comprises a curved airbag and a compressed gas cylinder connected to the curved airbag, and the control unit receives a three-axis (x, y, z) speed change value of the traveling space from the sensing unit, and then the memory The preset three-axis (x, y, z) speed change in the unit is compared with the pair value to determine whether the user has a fall condition, and if so, the control unit immediately activates the switch unit to make the compressed gas cylinder The gas inside is filled into the curved airbag, so that the curved airbag is rapidly inflated and popped out of the casing to achieve partial protection and soft shock absorption.本創作智能避險型身體保護裝置，包含殼體及設於該殼體一側並可固定於使用者身上任何位置的繫帶，該殼體內包含：充氣單元、開關單元、感應單元、記憶單元及控制單元，其中：該充氣單元，包含曲張氣囊及與該曲張氣囊連接之壓縮氣瓶，該控制單元自該感應單元接收行進空間三軸(x,y,z)速度變化值，再該記憶單元中預設之空間三軸(x,y,z)速度變化比對值相互比對判讀以判定使用者有無跌倒情形，若有，則該控制單元立即啟用該開關單元，使該壓縮氣瓶內之氣體充入該曲張氣囊內，使該曲張氣囊迅速膨脹彈出於該殼體外，達到局部保護及柔軟吸震的效果。
